摘要

A compact dual-band antenna designed for operating in IEEE 802.11b/g WLAN (2.4-2.484 GHz) and ITU frequency bands (8.01-8.5 GHz) is presented in this communication. The antenna has two distinct resonant modes generated with the help of three U-shaped transmission lines and a modified ground plane. A periodic repeating pattern of metamaterial unit cells integrated on the same plane of the substrate has enhanced the antenna performances using improved loading method. The measured bandwidth of the metamaterial-embedded antenna is increased by 16% in the lower operating band and 6% in the upper operating band. The compact proposed antenna provides wide measured bandwidths of about 40% (2-3 GHz) in the lower and 16% (8.19-9.63 GHz) in the upper frequency spectra. The maximum measured gain of the proposed antenna is increased around 3.63 dB at 2.36 GHz and 1 dB at 8.45 GHz. The proposed antenna radiator is about 89.6% compact with respect to a conventional antenna. An excellent agreement of the simulation with the benchmark results validates the design of the proposed structure.
